30CrNiMo8/1.6580 alloy forged steel shaft, OD80-1200mm'
Application: 30CrNiMo8/ DIN 1.6580 steel is widely used in the manufacture of the camshaft and connecting rod of engine parts, poor processability. 30CrNiMo8 is suitable for permanently stressed components with large cross sections for automotive and mechanical engineering.For economic performance under severe dynamic stress, parts must be designed for optimum strength or toughness.
Chemical composition: Carbon:0.26/0.34; Silicon:Max0.40; Manganese:0.50/0.80;
Chromium:1.80/2.20; Molybdenum:0.30/0.50; Nickel:1.80/2.20;
1)Preheat 1.6580 forged alloy steel carefully.
2)Raise the forging temperature up to 1150-1200°C.
3)Keep the forging temperature above 850°C.
9. Heat Treatment: Hardening&Tempering(quenched and tempered and after stress relieved)
1)Heating 30CrNiMo8 steel uniformly to 850°C;
2)W-Nr 1.6580 alloy steel should be quenched in the oil;
3)Heat the material to the temperature 550°C;
4)Soak at this temperature for at least 2 hours;
5)1.6580 alloy steel should be cooled in the furnace.
(In case after QT a straightening process is necessary then the products should be tempered and distorsion-poor annealed with at least more than 625°C.)
